MF-SM260-2-99

Overview

The MF-SM260-2-99 is a surface-mount polymeric resettable fuse from Bourns' Multifuse series. It features a hold current of 2.6A and a trip current of 5.2A, with a maximum voltage rating of 6VDC. The device dissipates 1.7W of power and withstands a maximum fault current of 100A. It has a typical trip time of 20 seconds and measures 7.98 mm in length. This component is AEC-Q200 rated for automotive reliability.

Feature Summary

Polymeric positive temperature coefficient (PPTC) technology provides automatic circuit protection by increasing resistance during overcurrent events.
Surface mount design facilitates automated assembly and compact PCB integration.
AEC-Q200 qualification ensures compliance with automotive electronic component stress testing standards.

Applications

Automotive electronics circuits requiring AEC-Q200 compliant protection
Low-voltage DC power distribution systems
Portable electronic devices utilizing surface mount components

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Check manufacturer archives or authorized distributors for confirmed substitute recommendations. Ensure replacement components match the original electrical ratings and package dimensions to maintain system integrity and compliance.

Selection Notes

Select based on the 6VDC voltage limit and 2.6A hold current requirements. Confirm surface mount compatibility with the target PCB footprint. Validate that the 100A maximum fault current capability meets the prospective short-circuit conditions of the application circuit without damaging downstream components.

Part Context

This component belongs to the Bourns Multifuse family of PTC resettable fuses. These devices offer reusable overcurrent protection as an alternative to traditional one-time fuses. The SM series specifically denotes surface mount packaging, designed for high-volume manufacturing environments where space constraints and automation efficiency are critical priorities.
